Ensuring High Manufacturing Standards for the Holes within Dynamically Loaded Composite Material Elements

Parts made out of composite materials are joined and connected by elements for joining into complex construction sections and subsections. Therefore it is necessary to fabricate numerous holes with different dimensions. Safety, quality and dynamic durability of such construction are in direct correlation with the hole quality. In this paper experimental research results of characteristic errors such as delamination, fuzzing, spalling, hole shape deviations, increased surface roughness, resin melting and superheating are presented. By adequate choice in hole fabrication means and manufacture regimes it is possible to fabricate high quality hole and thus ensure prerequisites for realibility of composite material elements under complex dynamical loads.
